Patent Images
1. A method, comprising the step ofusing a first wireless vehicular sensor node and a second wireless vehicular sensor node, each using a time synchronization message, comprising the step of:
- wirelessly receiving a first vehicular waveform report from said first wireless vehicular sensor node time-interleaved based upon said time synchronization message with a second vehicular waveform report from said second wireless vehicular sensor node;
wherein said first vehicular waveform report approximates a first raw vehicular sensor waveform observed by a first magnetic sensor operated by said first wireless vehicular sensor node, said first magnetic sensor observing a first vehicle;
wherein said second vehicular waveform report approximates a second raw vehicular sensor waveform observed by a second magnetic sensor operated by said second wireless vehicular sensor node, said second magnetic sensor observing a second vehicle.

Abstract
The invention includes using multiple wireless vehicular sensor nodes to wirelessly receive multiple, time-interleaved vehicular waveform reports from the nodes. Each vehicular waveform report approximates a raw vehicular sensor waveform observed by a magnetic sensor at the node based upon the presence of a vehicle. The vehicular waveform reports are products of this wirelessly receiving process. The invention includes apparatus supporting the above outlined process. The vehicular waveform reports may be time synchronized.
